Android :: Changing Variable Affects Indirect Variable (value Vs Reference)

Sep 26, 2010

Is copying the reference to the object and not the value of the object. Meaning, when I modify pos.top or pos.bottom, the original object gets modified. I'm guessing I am missing a concept of pass object by reference vs value here which I thought I understood. What is the fix here? Is it a problem with how I defined my custom class?

Android :: Add Maven Classpath

Mar 2, 2010

My project requires some external libraries to build in in Eclipse. They live in /trunk/lib whereas my project is in /trunk/projectA.To get Eclipse to find the libraries on all machines we set a variable PROJECT_A_HOME.Now I'm trying to get some builds going with maven and I can not figure out how to add that path (be it environmental variable or relative to $(basedir)) to the build. I really do not want to set up a repository for these dependencies, as I keep them in source control and want builds to continue to work in Eclipse.

Android :: Intercepting WebKitView Resource Requests / Serving From Classpath

Jun 7, 2010

I'd like to create dynamic HTML in my app that will also include referecences to a few images. The images should not be resolved / requested by the internet, but instead I would like to somehow intercept these calls and then respond will classpath resources to those requests.I think this is similar how phonegap or titanium do this, but this is just an assumption.Does anyone know how webkit's resource loading can be intercepted and resources can be served from a local cache/ classpath intead of contacting the internet?

I am working to set a countdown timer. I have successfully (borrowed) a number picker (spinner) and set up the dialog box for the user to set the time.

Android :: Getting Variable Out Of Public Void

Apr 21, 2010

I have this code:
hubSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parentView,
View selectedItemView, int position, long id) {
final MediaPlayer mp2 = MediaPlayer.create(Textbox.this, R.raw.hero);
mp2.start(); } public void onNothingSelected(AdapterView<?> parentView) {
} } );

(The code basically runs when a new item is selected of a spinner and then plays a song, which later will be a variable based on what was picked, but I'm fine as it is for now). And I want to be able to use 'mp2' out of this public void, (I want a button which pauses it). How can I do this?

This is great for listening to podcasts in a fraction of the time. Depending on the original audio, I can generally make everything out up to +25%.

Android :: Static Variable Instantiation

Apr 1, 2009

I have noticed in my application(s) that after a call to Activity.finish() that the static variables that I declared in my classes still hold the values that they were changed to during the activity's life cycle. Upon the re-launch of the activity, the program does not re-instantiate the variables as declared or set them to the default java behavior. Is there something that I can do to cause this to happen, other than re-setting every static variable in my application?

Android :: How Do I Refer To Drawable With Variable

Sep 13, 2010

I am doing an app related to football. I have a list view that will have various rows representing teams. In my custom array adapter I want to write some code that will present an icon for the team represented by the row. I have a drawable resource for each team (for instance for Indianapolis, Ind.png). In my code I can't refer to "R.drawable. Ind" because the Ind part is dynamic. That value would be in an array, like TeamArray[position]. As I expected, I certainly can't use R.drawable.TeamArray[position] because it won't even compile, it expects a literal name from the drawable folder. Is there a way to do this?

Android : Way To Get Variable Values Back?

Feb 6, 2010

I seriously need help with a quite strange problem. I created a client which communicates with a server. Therefore, I have three classes. An activity providing a nice dialog to configure some data, a background service which checks the connection status periodically and a server class which handles the socket connection. Originally, the background service owned a server connection object but because I could not manage to provide data from the activity to the service, I decided to create the server connection class as singleton. The user is now able to change data in the activity (IP, Port, Username, Password) which shall be transmitted to the server object, if the save button is pressed. The data is read correctly, the activity calls the setter of the server class and the logcat also says that this data is correctly applied to the variable that stores the data in the server class. However, if I try to start the socket connection still the old values are stored in my variables although they've been overwritten before. What I am doing wrong, or how can I fix this?

Android :: Passing An Order By Setting Variable

Jul 24, 2010

I have a list view with several columns; things such as name, date, etc. I want to be able to click on the header TextView and sort the list by that field. When the list loads the variable works, and a list is queried and sorted by the field _id (no surprise other than it works), but when i click on the header TextView I get a force close:

Thread [<3> main] (Suspended (exception SQLiteException))
ViewRoot.handleMessage(Message) line: 1757
ViewRoot(Handler).dispatchMessage(Message) line: 99
Looper.loop() line: 123
ActivityThread.main(String[]) line: 4595
Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method]
Method.invoke(Object, Object...) line: 521
ZygoteInit$MethodAndArgsCaller.run() line: 860
ZygoteInit.main(String[]) line: 618
NativeStart.main(String[]) line: not available [native method]

The TextView gives no errors when not changing my orderby variable.
Setting Variable:

private View.OnClickListener NameSortbtnListener = new View.OnClickListener(){
public void onClick(View v){
sort = " KEY_JOURNAL_TITLE ";
fillData();
} };

Populating List:
private void fillData() {
Cursor notesCursor = mDbHelper.fetchAllJournals(sort);
startManagingCursor(notesCursor);
String[] from = new String[]{journalDbAdapter.KEY_JOURNAL_TITLE,
journalDbAdapter.KEY_LOCATION, journalDbAdapter.KEY_JDATE,
journalDbAdapter.KEY_STEPS};
int[] to = new int[]{R.id.text1, R.id.text2, R.id.text3, R.id.text4};
SimpleCursorAdapter notes =
new SimpleCursorAdapter(this, R.layout.notes_row, notesCursor,
from, to);
setListAdapter(notes);
}

Query (In DB Adapter):
public Cursor fetchAllJournals(String sort) {
return mDb.query(DATABASE_JOURNAL_TABLE, new String[] {KEY_JROWID,
KEY_JOURNAL_TITLE, KEY_JOURNAL_NOTES, KEY_JDATE, KEY_LOCATION,
KEY_STEPS},null , null, null, null, sort ,null);

Android :: Variable Rate Audio Playback

Mar 14, 2010

I'm new to development on Android and thought maybe you could shed some light on my problem. I'm trying to code up a little object to take care of playing a list of songs at a constantly varying playback rate. I just spent a god chunk of time getting it going with SoundPool only to find out about the undocumented 1 mb file limit. Do you guys have any ideas? Should I be using AudioTrack? I was going to try that next. Any tips or code samples for doing this kind of thing? It's such a shame that neither JetPlayer nor MediaPlayer support rate changes.

Android :: How Do I Load URL That Requires Login Into Variable

May 1, 2010

I am trying to port my usage meter from a JavaScript Gadget (win) / Widget (OSX) to Android. Total newbie when comes to JAVA + Eclipse + Android 2.1 SDK. Essentially what I want to do is load a page, pass through a username and password and load the resulting page into a array that I can then run some regular expressions through.

My code from JavaScript (I've replace the actual URL with a dummy one) is:

xmlhttp.open("post","https://acme.com.au/your_account/index.php?function=login",false);
xmlhttp.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT");
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlhttp.send("check_username=" + username + "&password=" + password);


I need to know the Android equivalent to the above please. I've played around with WebView but that loads the page in a web browser which isn't what I want.

Android :: How To Implement Custom View With Variable Fields?

Jul 7, 2010

I have a ListView that displays a set of notes, each with varying ammounts of data (i.e. some have a due date, others don't).Currently, each view in the list is a RelativeLayout containing a TextView for each field, plus two Button and a CheckBox. I then simply hide the unused fields by setting visible false on each one.This has worked well, but I'm about to add a lot more data fields to the notes and inflating that many unneeded views for each row will surely kill my app. I need a more dynamic solution.I've decided the best way to go is to create a custom view. How can I implement/design my view so that it can display a variable number of text fields without creating/ destroying textviews each time (which would be quite expensive and worse than my current situation), or maintaining a large pool of hidden textviews?

Android :: How To Deal With Application Widget Having Variable Sizes?

Apr 24, 2009

I want to create an app widget that could take up a different number of "cells" on the home screen, but I don't think that the app widget framework easily supports this. I know that an app widget can have a configuration screen, and I'd like the user to be able select a sort of small, medium, or large size for the widget as part of my configuration activity. Unfortunately, I don't think that this is possible, correct? Based on the minWidth and minHeight properties, the Launcher app will assign a number of cells that I can't configure at run time.

For instance, if I want a weather widget that has a current, hourly and weekly format that take up 1, 2, and 4 cells respectively, I can't do this at run time. Instead, I believe my only option is to export 3 different widgets and have them all listed in the widget picker dialog as something like "Weather - current conditions", "Weather - hourly forcast", and "Weather - week long forcast".

Android :: Best Approach For Making One Variable Available In Another Activity / Class?

There may be the option to write the result of the OnListItemClick int position into a small SQLite DB - but that seems to be total overkill.

Anybody could pls share the best approach with me?

Android :: Dynamic Preferences For A Variable Number Of Profiles In App

Aug 22, 2010

I am looking for a way to create dynamic preferences where I don't need to hard code the preference key and I could have a variable number of preferences. Basically, my application will let the user create a multiple number of profiles and each of these profiles will save custom values for a fixed number of preferences. So this way, the user does not have to change the preferences every time he wants this app to run differently, he can just switch the profile. One way I think will work is by subclassing all the standard Preference classes and calling their setKey method with my custom preference key, containing the profile name, but this is ugly. So is there a cleaner and more standards compliant way to do this?
